Internal operating errors
Internal operating errors can be due to inadequate installation or layout, such as excessive temperatures
due to poor selection of the inverter’s location, or to an internal fault. A service technician and Solectria
Renewables should be consulted if this fault arises.
Operating faults
Code
Designation
Condition
Solution
301
Internal fault on the device or a
blown GFDI fuse.
The device switches off.
Check the GFDI fuse.
Please contact your installer/service
technician or Solectria Renewables.
We recommend switching off the
device to prevent any damage
occurring to it.
302
Excessively high temperature.
The device switches off and
switches back into power/grid
feed mode when the temperature
has dropped down to normal
operating temperature
Check to ensure that the device is
not being directly subjected to
sunlight. Please observe the
description of the mounting. Please
contact your installer/service
technician or Solectria Renewables
if this measure does not eliminate
the fault.
Ground Fault:
If a significant ground fault occurs in the PV array or wiring, the GFDI fuse (located on the
wiring/connector panel) may be blown. If it is, determine and repair ground fault and replace fuse with
Bussmann GBB-1 250VAC or Little Fuse 3AB 1A 250VAC 314001.
If the GDFI detects a ground fault current larger than 0.8A, error 506 will be displayed. In addition to that
the current value can be read in the display.

Weak Sunlight Condition
:
Operation in weak sunlight, (for example early in the morning, when overcast or when snow is covering
most or all of the PV array) can cause the inverter to go through a cycle of trying to start and restart
several times. If you see: “Wait for restart”, “Sync to AC grid” and “Solar voltage too low”, “Solar
power too low” on the LCD display, you have weak array out put power. Look again when the sunlight
is stronger, clouds have cleared or snow has melted or fallen off of the array. It is possible that the length
of time in the morning that this type of condition appears could gradually increase. This might indicate
that there is an excessive build-up of dust or debris on the PV array. If you notice this condition, check
and wash the array for maximum performance.
It is possible that during these low power operating conditions the display shows error
301. This is normal. If this error occurs during startup, this error can also be ignored.
